A numerical scheme to analyse the forward problem in microwave tomography systems is introduced in this paper. Wire‐volume electric‐field integral equations are given to describe the electromagnetic environment in microwave tomography systems. The 1D triangular function and the 3D volumetric rooftop function are chosen as the basis functions to approximate the unknown electric current in the antennas and electric flux density in the object. The bi‐conjugate gradient method is employed to solve the system of linear equations. A comparison of the measured results shows that this scheme is efficient for simulating microwave tomography systems. © 2004 Wiley Periodicals, Inc.
